  1. Hi. I have copied this post from an earlier one. I am looking for a fast and practical way to calculate horizontal, vertical and true distances between specific points in boreholes. Specifically, I am referring to lost circulation zones (LCZ) that occur at different elevations in different boreholes. For example, in directional well 34 I have LCZ at 625, 1100 and 1400 meters depth and in well 5 which is a vertical well I have LCZ at 700 and 1000 meters depth. I have also got a hypothetical borehole trajectory for an undrilled well (8b) that passes near to both wells 34 and 5. Based on the local fault network, well 8b may not find a LCZ until 1350 m. I would like to use Rockworks to easily determine the horizontal, vertical and true 3d distance between the LCZ in wells 5 and 34 with respect to the undrilled well 8b. The best way that I have come up with is to go into the borehole orientation table for wells 5, 34 and 8b and copy the xyz coordinates at the specified elevations into Utilities table and then run the 3D lineation program. This works but it is not intuitive. Could you include within he borehole data base a menu option (possibly within the same TD program) that allows me to specify the elevation or depth in specific enabled boreholes so that in effect they are read as if they were TDs and then the program gives results based on these parameters. I think that this would be the same as temporarily changing the TD of each borehole that is being analyzed to the depth / elevation where lost circulation zones occur or are expected to occur. I am attaching some sample data so that you can create the borehole paths and calculate the distances between the lost circulation zones based on the borehole paths. Well 5 Well 34 Well 8b Well type Vertical Directional Undrilled Easting 285000 285150 284900 Northing 950000 950300 949900 Azimuth NA North Northwest Elevation 700 700 TD 1500 1600 Lost circulation zones 700 625 1000 1100 1400 Given the borehole location data, create a borehole path for wells 5, 34 and hypothetical well 8b such that the horizontal, vertical and true distances can between the lost circulation zones in wells 5, 34 and 8bcan be calculated easily. *All values are reported in measured depth.
  2. Using the TD tool in the Borehole Manager

    Hi Tom, I have seen that video and although I don't have a 3D model of my field area I can hypothesize xyz coordinates that I want my welfare to pass through. The problem that I have with that is that when I want to reproduce the vertical part of the well down to, say 300 meters, the borehole starts to curve before that depth which would not reproduce a realistic curve. Previously you wrote that aligning three points with the same xy coordinates and a decreasing z coordinate (600, 301, 300 elevation) may resolve this problem however, I have yet to try this because I was getting an error that says that the program needs at least two points to run (even though I had already defined various points with different xyz values.
  3. Hi, I have been having a lot of trouble exporting high resolution images from rockworks as png files. This topic was addressed by Tom Bresnahan via e mail and since I have decided to try to export the Rw2D file as a georeferenced png to SURFER to reproduce it there. When I export from SURFER as a png the quality is excellent which brings me to another observation and posible bug within the Rockworks program. When I export as a png file from SURFER, as I increase the number of pixels the size of the document increases, the exact opposite occurs with Rockworks. I have also sent an e-mail on this topic with a screen shot of what I am talking about.
  4. You are right, this behavior is very strange but be it as it may when I increase the size of the page the number of pixels (scale) subsequently decreases. Unfortunately the screen shot that I sent to you didn't go through with very good resolution because you would have seen clearly by the numbers that the image scaling behavior is seemingly backwards. I am on a network so I do not have access to the installation disks. However, do you think that it may be necessary to reinstall the program?
  5. Using the TD tool in the Borehole Manager

    Hi Tom, I just uploaded three RwDat files to rockware.com/upload/. The well names are different but the exercise is the same. Well 1 is vertical, well 12 is deviated and well 14 is undrilled but will be deviated towards the northwest. How do I go about determining an optimum well path that will keep me furthest away from the lost circulation zones of both Wells 1 and 12 without dropping the azimuth below 315º?
  6. determine optimum path xyz points

    Hi, I am having difficulty using the Determine Optimum Path XYZ Points tool. I enter a series of data and when I try to run the program it says that it needs at least two points, regardless of the fact that I have entered 3 different xyz pairs and properly defined the units. Listed are the xyz values from left to right. 350000 1190000 600 350000 1190000 301 350000 1190000 300 350100 1190050 200 350300 1190250 -1300 350500 1190500 -2000
  7. PDF export (and others)

    Hi Mitch, As a matter of fact I have tried increasing the Pixels per inch as well as resizing the exported png file and the higher the resolution I use the thinner the lines are. That is the opposite of what I want to accomplish. I want to créate maps that show significantly thicker lines to represent specific borehole paths or faults and thusfar I have not been able too. Any other suggestions? What is the e-mail address of support so that I can send the files to you and maybe that way see the difficulty that I am experiencing.
  8. PDF export (and others)

    Hi Mitch, Thank you. I still don't understand the limitation that exists with PDF but that's OK. I perfectly understand the mathematical calculation of the pixel count so that is not the issue. However, the 4"x 3"image size that you suggest leaves me with a rather low resolution image. I have tried upping the resolution by creating an image that is 20"x 15"which increases the number of pixels (great) and gives me a high resolution image in MS Word (great). Regardless, the line widths are compensated (NOT GREAT). In other words thick lines in Rockworks are visualized as thin lines in MS Word (Bummer). Can you give me some advice on how to overcome this graphics limitation?
  9. Digitizing points in RW2D

    Hi, With the digitize points option in RW2D I would like someone to explain to me the use of this tool. I mean, after digitizing the points how do I go about saving those locations? For example, I don't see any kind of point table as there is for polyline or polygons.
  10. Digitizing points in RW2D

    Thanks Molly, So if I use option 4, should I be able to create a new point map and append it to the 2D image that I am working on? If I only mark one or two points that creates a problem because the Easy Map tool in Utilities needs at least three points to make a simple point map (even though contours are not necessary). I think that in an earlier post this issue was addressed but has yet to be modified with a new upgrade.
  11. PDF export (and others)

    Adobe Illustrator can edit SVG images. I am sure that Corel Draw can as well.
  12. PDF export (and others)

    Hi Mitch, Thank you for you comment. I don't understand why PDF would be too difficult to integrate as a file export type but I suppose that there must be a reason (). On the other hand, I figured that the resolution of my images had to do something with the scalability but I have noticed that when I change the pixels per inch the program automatically changes the image dimensions. How do I manage that the image keeps its same dimensions when I change the amount of pixels per inch?
  13. Using the TD tool in the Borehole Manager

    I tried copying the above tabulated data into the text editor and it came out as a single column. When I try to attach a file the I am only allowed to upload a file that is 234 Kb or less (kind of inconvenient). Is there a way to increase the permitted file upload size?
  14. Closest Point option not working

    Hi, I am trying to use the Closest Point option with Rockworks 16 and it seems that it is not functioning correctly. I don´t get any kind of result whatsoever.
  15. Closest Point option not working

    OK. It looks like the problem is that I need to create a RwGRD first.
  16. Thanks Tom, I have another question. In the directional borehole trajectory sheet there is in the row dropdown menu to "go to" the first last or to a specific row number. Can that be modified so that I can select a specific value en any one of the data columns (specific true vertical depth or specific elevation, for example)? This would be really useful.
  17. Multiple striplogs of deviated wells against TVD

    Hi, I have experienced the same difficulty that Julia mentions. Just as Tom suggests, the only that I have found to create vertical logs of deviated well data is to make a copy of the well and change the azimuth to a constant value. However, I have found that setting the azimuth parallel to the view direction rather than perpendicular to it works fine for me. Regardless, a TVD log feature is imperative for a program like Rockworks and should be an "out of the box tool". For example, I believe that STRATER comes with the capability to create TVD logs alongside MD logs with no problem. This should not be a complicated change for Rockworks. Edward
  18. Snapping to lines and verticies in RW2D

    Hi Mitch, I will try to get an example to you so you can see what I am trying to do. The other thing is . . How are the Smart Snap points defined? Can they be user defined?
  19. Utilities Survey | XYZ -> Optimum Path, Request for Go To

    Hi Tom, Thanks. I have tried that but for example when I filter those values they do not necessarily get displayed in the order that I need. Is there a way to predetermine or at least reorder the rows so that they are ascending or descending based on the values en a given column?
  20. Hi, I am am using Rockworks 16 V.5 and am trying to display XYZ data columns in the data tables of the Borehole Manager but I do not see the menu option View/Show XYZ values option indicated in the Rockworks 16 Help file.
  21. displaying xyz values in data tables

    Yes Molly. For example, there are lost circulation zones (LCZ) at different elevations in different boreholes and I would like to use Rockworks to easily calculate the horizontal, vertical and true distances between them. For example, in directional well 12 I have LCZ at -270, -370 and -540 meters elevation and in well 1 which is a vertical well I have LCZ at -148 and -350 m elevation. I have also got a hypothetical borehole trajectory for an undrilled well (14) that passes near to both wells 12 and 1. Based on the local fault network, well 14 may not find a LCZ until -620 m. I would like to use Rockworks to easily determine the horizontal, vertical and true 3d distance between the LCZ in wells 1 and 12 with respect to the undrilled well 14. The best way that I have come up with is to go into the borehole orientation table for wells 1, 12 and 14 and copy the xyz coordinates at the specified elevations into Utilities table and then run the 3D lineation program. This works but it is not intuitive. Could you within he borehole data base something like a menu option (possibly within the same TD program) that allow me to specify the elevation or depth in specific enabled boreholes so that in effect they are read as if they were TDs and then the program gives results based on these parameters. I think that this would be the same as temporarily changing the TD of each borehole that is being analyzed to the depth / elevation where lost circulation zones occur or are expected.
  22. xyz survey calculation error

    Hi, In the Create Optimum Path Borehole Survey Table I select that the inclination should be listed as (Down = 0). However, the result is in terms of (Down = -90). This creates a problem when I copy and paste these values into the borehole manager because the borehole path does not plot correctly.
  23. xyz survey calculation error

    Thanks Tom, I'll try that and let you know.
  24. Hi, I am having a problem when I choose to change the values in a borehole orientation table. When I am planning a well, I frequently need to try different borehole construction arrangements and it is very convenient to just save a rwDat file of the Depth, Azmith and Inclination data and then just open it or close it as I need to to replace the current data. This works quite well but rather frequently I get an error message that says something like "Could not update the file because some data may have been changed since the last time it was opened" Could you look into this?
  25. Problems with the Borehole orientation table

    OK, thanks Tom. The next time that the error message comes up I will send you the actual text that comes up in the error message. It may be due to an error in the network connection, however I only notice this type of problem when I interchange different orientation table data. Normally, if it is only a matter of adding new data I do not get an error but changing entire tables still frequently cause an error.
